Is there a way for the donor to update their payment method for recurring donations?
When a donor makes a recurring donation (either as a regular recurring donation or as part of a membership subscription), they are sent a confirmation email with a link that allows them to view and manage their recurring payment settings, including the payment schedule and their card-on-file. This url is https://www.betterunite.com/portal which they can visit at anytime. This information is provided with every recurring payment confirmation email as well. The donor can use the verification-based login mechanism on this page to access their own schedule page and manage their card on file at anytime.
